To convert tesamorelin to syringe units, divide your dose in milligrams by the vial’s concentration in mg/mL, then multiply by 100. Concentration equals vial strength divided by the milliliters of bacteriostatic water you add. Example: 1.4 mg at 4 mg/mL = 35 units on a U-100 syringe. Arithmetic only, not medical advice; verify with a licensed clinician.
Tesamorelin reconstitution & dosage calculator X
Reconstitution / draw volume / syringe units / supply-chain
Arithmetic checks out. Confirm clinically, against the label, and against the actual vial before any use.
Independent check - dose mg / concentration mg/mL = volume. U-100 units = mL x 100.
EGRIFTA SV: 1.4 mg once daily. Label mixes a 2 mg vial with 0.5 mL and withdraws 0.35 mL
For the labeled product: 2 mg / 0.5 mL = 4 mg/mL; 1.4 mg / 4 = 0.35 mL.
Use only for the labeled indication and exact formulation; IGF-1/glucose monitoring is outside this calculator.

Same-syringe co-draw. Reconstitute each peptide in its own vial, then draw them into one syringe.
- Reconstitute each peptide in its own vial — never add water to multiple peptides in one vial.
- Only co-draw peptides with the same diluent (e.g. both bacteriostatic water) and compatible pH.
- Draw and inject fresh — do not pre-mix and store; mixture stability is not established.
- No blended stack is clinically validated. Verify each component and confirm with a clinician.
Tesamorelin dose to syringe units: reference chart
| Vial + water | Concentration | Units per 1 mg | 1.4 mg |
|---|---|---|---|
| 5 mg + 1 mL | 5 mg/mL | 20 | 28 |

| 5 mg + 3 mL | 1.67 mg/mL | 60 | 84 |
| 10 mg + 1 mL | 10 mg/mL | 10 | 14 |
| 10 mg + 2 mL | 5 mg/mL | 20 | 28 |
| 10 mg + 3 mL | 3.33 mg/mL | 30 | 42 |
| 20 mg + 1 mL | 20 mg/mL | 5 | 7 |
| 20 mg + 2 mL | 10 mg/mL | 10 | 14 |
| 20 mg + 3 mL | 6.67 mg/mL | 15 | 21 |
Concentration = vial strength divided by the bacteriostatic water added. On a U-100 syringe 100 units = 1 mL, so units = (dose divided by concentration) x 100. Values are syringe units, not milligrams. Amber values exceed 100 units, which is more than one standard 1 mL U-100 syringe holds, so that combination needs a more concentrated solution. Columns are the dose steps named on the current FDA label - they describe what has been studied or labeled, not what anyone should take, and this page gives no dosing advice. Multiply the units-per-1-mg figure by your own dose in milligrams to convert any amount. For vial sizes or doses not shown here, use the general mg to units converter.

Frequently asked questions
What is tesamorelin actually approved to treat?
It is FDA-approved only as EGRIFTA SV, indicated to reduce excess abdominal fat in people with HIV-associated lipodystrophy (FDA label 022505s018). The labeled regimen is 1.4 mg injected under the skin once daily. It is not approved as an anti-aging, muscle-building, or general wellness product, and this page reflects only that labeled formulation and its math.
Does tesamorelin come with an official reconstitution example I can check my numbers against?
Yes, and it is unusual in that respect. The EGRIFTA SV label gives a worked example: you reconstitute the 2 mg vial with 0.5 mL of the supplied diluent to get 4 mg/mL, then withdraw 0.35 mL, which reads as 35 units on a U-100 syringe, to deliver the 1.4 mg dose. This calculator reproduces that same mg-to-units arithmetic for whatever concentration you enter.
Is this calculator meant for the commercial EGRIFTA SV kit?
No. The branded EGRIFTA SV product ships as its own single-dose vial with a specific supplied diluent and fixed mixing steps, so follow that package insert if you have the commercial kit. This tool is a general mg-to-units helper for a vial you reconstitute yourself, where you choose the diluent volume; use the BAC water calculator to pick that volume.
Why does the label describe a 2 mg vial when mine is 5, 10, or 20 mg?
The FDA-labeled EGRIFTA SV strength is a 2 mg single-dose vial. Vials found outside that branded product are commonly sold in 5, 10, and 20 mg sizes, which simply hold more powder. The milligrams of powder do not set your dose on their own, the concentration does, so a 10 mg vial and a 2 mg vial can both be drawn to the same 1.4 mg once you account for how much diluent was added.
Can this tool tell me how much tesamorelin to inject?
No. It only performs arithmetic, turning a milligram amount into the volume and U-100 units that match the concentration you enter. It does not set, recommend, or personalize a dose, and it is not medical advice. The only labeled dose is 1.4 mg once daily for the approved HIV-lipodystrophy indication; confirm anything you actually inject with a licensed clinician.
